Title: Offset adjustment device
Inventor: ASAKA KOICHI
IPC: G05B1/02
Filed: 1990-11-28
Abstract: PURPOSE:To obtain necessary resolution in an A/D converter with low bit precision by determining the pulse width of the PWM signal by an arithmetic unit and indicating it to a PWM signal generator, and obtaining an offset adjusting voltage from its generated PWM signal and adjusting the offset of an input signal at all times. CONSTITUTION:The arithmetic unit 12 reads the offset value of the input signal out of a signal sent from the A/D converter 11 and indicates the pulse width of the PWM signal to the PWM signal generator 14 so as to adjust the offset. The PWM signal generated by the PWM signal generator 14 with the indication is passed through a low-pass filter 15 and converted into the specific offset adjusting voltage, which is used by a differential amplifier 16 to adjust the offset. Consequently, the input signal which has the offset need not be in the A/D conversion range of the A/D converter 11 at any time and the A/D conversion range is small, so high resolution is obtained.

Title: Japanese word processor
Inventor: SUZUKI SHUNICHI
IPC: G06F17/21
Filed: 1990-11-29
Abstract: PURPOSE:To improve the operability of a Japanese word processor by changing automatically the character spaces in a table without correcting the characters in the table and reducing horizontally the table with no erasion of characters. CONSTITUTION:A table correction instructing part 1 instructs an intra-line character discriminating part 2 to discriminate whether a table can be horizontally reduced or not. If so, a table correcting part 4 is started and reduces horizontally the table. If not due to a fact that the number of digits has no margin for the characters included in the table, a character space adjusting part 3 is started and reduces the character spaces for the character strings of each line in the table. Thus a margin is secured with adjustment of the character spaces and a table correcting part 4 is started to horizontally reduce the table. As a result, the operability is improved for a Japanese word processor.
